I have been using v3.442 and its saved my a$$ more than once. I especially like it for trying out new software with out really installing the software! Now that v3.46 is out Ive noticed a nice increase in my browser startup time ,not that it was terribly bad before but I do think its faster now...atleast with Firefox. Sandboxie is awsome and it just keeps getting better. Thanx tzuk.
